Innovative materials and artisanal craftwork in a stunning multi-component structure: Delivering the sophisticated refinement of traditional Japanese aesthetics
Introducing a new addition to the 2100 line of G-SHOCK Iconic Styles on par with the 5000 line, now proudly bearing the MR-G name. While retaining the comfortable sizing and fit on the wrist, the new MRG-B2100 features a full-metal exterior employing state-of-the-art materials and hand-finishes applied by master craftspersons. Polishing is applied to each component of the multi-component structure prior to assembly to create a sophisticated yet tough beauty down to the very finest details. The dial features a design concept inspired by kigumi, the art of traditional Japanese interlocking woodwork, expressing a passion for traditional Japanese aesthetics and craftsmanship.


Multi-component structure enabling most sophisticated polish ever
The bezel is formed from a total of 27 separate components instead of a single piece. Each part is polished prior to assembly to give the watch a distortion-free finish, right down to the most challenging spots, like recessed portions. The band, too, has dimpled portions constructed with separate componentry. The artisanal craftwork shines through each and every component — just look at the stunning, distortion-free mirror finishes created with Sallaz polishing.

Multi-Guard Structure with the toughness to support an intricate form
Buffering is inserted between the parts of the multi-component bezel and case, providing excellent shock-absorption to help absorb impacts to the module.

Super-hard alloys developed in Japan, combining strength with beauty
The top bezel is made with COBARION, an alloy boasting a hardness about four times that of pure titanium and a brilliant gleam comparable to platinum. The band links employ DAT55G, a titanium alloy with a hardness about three times that of pure titanium that offers excellent processability. With these super-hard alloys developed in Japan, Casio achieved an exterior design that ensures both strength and beauty. A special Ti64 titanium alloy is used for the case, case back and buttons.

Dial design inspired by kigumi concept from Japanese aesthetics
The dial design incorporates special decorative aspects inspired by traditional Japanese kigumi wooden joinery techniques. The base surface is given a corrugated form with an intricate series of openings to create a geometric pattern beautifully expressing a latticework worldview. The elaborate series of openings in the face let enough light through for solar power generation, allowing the dial to be given a profound metallic black finish. In addition, the index mark at 12 o’clock features an intricately assembled two-part structure. This kind of craftwork, which demands the very highest precision, is only possible thanks to the fine processing technologies of Yamagata Casio.

Kigumi
Kigumi is a traditional Japanese construction method and woodworking technique used for wooden joinery without the use of nails or other metal fittings. It has been employed since the Heian period (794–1185) to build wooden structures, including shrines and temples, as well as wooden fixtures. With the stunning degree of precision the technique uses to create forms with both structural strength and artistic design sensibility, kigumi is considered an artisanal form of craftwork. Such wooden framework techniques producing intricate geometric patterns can be observed in traditional handicrafts, as well.

DETAILS

Slim case with a shock-resistant crown
A slimmed down form of the original MR-G Clad Guard Structure allows the incorporation of componentry to guard the crown. This makes it possible to maintain the streamlined profile of the 2100 line while also giving the crown shock resistance. A special construction keeps the MR-G logo, engraved on the crown, horizontally aligned when the crown is screw-locked.

Solar-powered timekeeping with Bluetooth® and radio control for enhanced accuracy and reliability.

Super Illuminator(high-brightness LED light)for maintaining watch readability in the dark.

Scratch-resistant, highly transparent sapphire crystal with an anti-reflective coating.
